China's top drug official, Liu Yuejin, said the plan was to bomb the drug lord’s hideout in northeastern Burma using unmanned aircraft. The comments by the official are a sign of China’s increasing development of unmanned aerial technology. For years, the United States has led the global drone market. In recent years, China has greatly improved its drone technology. The country is also modernizing its global navigation system to compete with those of the United States, Russia and Europe.
